The "clean filter" light is on all the time on my dehumidifier, even if I remove the filter and clean it. This is a Frigidaire FAD504DWD from December 2013 (manufacturing date on label). Can anyone tell me:
1. Should I test anything before going further, or should I just order a filter?
2. Since these things are little refrigerators / air conditioners, how do I know whether it is still running efficiently? Is there testing to do?
3. Is this thing close to its service life? I clean the filter with a soft brush whenever the light comes on (which until now would allow the "clean filter" light to go out. The dehumidifier runs for about 9 months of the year in a mildly dusty basement that doesn't have a big water problem. It drains directly by hose to a floor drain and seems not to have any problem keeping the basement at around 55% RH.
Thanks.
